Mueller Streamline CPL00350 Reducing Coupling 1x5/8 Cxc

Product Description

The MUELLER STREAMLINE CPL00350 is a wrot copper reducing coupling designed for sweat (CxC) connections in copper tubing systems. It transitions from a 1-inch connection to a 5/8-inch connection, making it a standard choice for reducing pipe runs in residential and commercial plumbing and HVAC refrigerant piping. Fabricated from wrot copper, this fitting delivers reliable pressure integrity and clean soldering characteristics. It meets ASME and NSF standards, confirming suitability for potable water and mechanical systems. Licensed plumbers and HVAC technicians install this fitting as part of new construction and retrofit work wherever a diameter reduction is required in a copper sweat assembly.

This reducing coupling is used in residential and light commercial plumbing supply lines, hydronic heating systems, and HVAC refrigerant or condensate piping where a sweat-connected diameter reduction is needed. It is appropriate for any application requiring a CxC reducing joint in copper tubing. The fitting is suited to both above-ground and accessible in-wall or ceiling installations where copper sweat fittings are the specified connection method.

Key Features

• Wrot copper construction provides excellent thermal conductivity and consistent wall thickness for reliable sweat joints
• 1-inch by 5/8-inch reducing configuration handles common diameter transitions in copper piping systems
• CxC (sweat) connection type on both ends for standard torch-soldered assembly
• Meets ASME and NSF compliance standards for use in potable water and mechanical piping
• Compact body at 1.78 inches in length simplifies installation in tight spaces

Compatibility

Designed as an OEM-style sweat fitting compatible with standard copper tubing in 1-inch and 5/8-inch nominal sizes per ASME standards for wrot copper and wrought copper fittings.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician following applicable local plumbing codes and ASME guidelines. Shut off and depressurize the supply line and drain standing water before cutting into existing piping. Clean and flux both the fitting sockets and tube ends thoroughly before applying heat to ensure a full, void-free solder joint. Do not apply excessive heat to the fitting body, as overheating wrot copper fittings can compromise joint integrity.
